'TO ALL WHOM'IT MAY CONGERN:

Be it known that I, ELIJAH FJDUNAWAY, of Indianapolis, county of Marion,and State of Indiana, have invented new and useful improvements inMachine for Wiring Blind-Rods and Sla-ts; and'I do hereby declare 'thefollowing to be a clear and exact description thereof, reference beinghad to the accompanying drawings,

:and tothe letters of reference marked thereon, making a part of thisspecification, in which- Figure 1 represents a top vieu' of ,thcmachine.

Figure 2,1m end elevation.

Figure 3, a back view.

Figure 4, the slide and set-screw.

Figure 5, an end view of the slide and set-screw.

Figure 6, a view of the plates and eye in which the driver operates.

Figure 7, an end View of said plates and eye.

The nature of my invention consists in an adjustable eye, formed ofsteel plates, 'that the staples pass through, to be adjusted foi-wide ornarrow staples, and of hardened steel, so as not to wear; also, theleather cord ,and pulley, as arranged and attached to both levers. A

A the frame or bed-plate; B the upright stationary post, in whichthemain` .leverC and staple-driver D operate; E the incline blade orbearer, upon which the staples are placed, and slide down to where theycome in contact with the driver D that presses them down into the slator rod beneath. His a sliding notched rod, moved by the action of thespring-lever J, and gives the regular and exact distahcesfor each stapleto be driven .down into the slat or rod as it passes under the driver D.The slide K and set-screw L are used to centre the slats. The spring Nholds the notched rod H to its'place. P, the upright post, (with aspring beneath,) to which the main lever C is,pivoted. -The slide Q isregulated by set-screws, R, and so adjustable to be moved back and forthto centre the staple in thick o1' thin slats or rods. At the one side ofpost Bis a pulley, S, .against which a leather round strap, T, operates,the strap or cord T being connected by a hook and eye to the lever C,and by another hook and eye to 'the spring-lever J; the cord drawing thelever `J forward, and the :spiral spring U forcing it back again; thespring being attached to a short upright post, V, to the top of whichthe lever J is pivoted. `The Vdriver D operates in a groove in the lowerend of a plate on the post B. The lower en d of the brass or metal platehas a box or eye, W, (as seen at figs. 6 and 7,) with steel plates, X,that are adjustable, closer together or drawn apart to suit wide ornarrow staples, the steel plates also preventing :the wearing ofthe eyeon either side, and .are adjustedto either side by a slot and adjustablescrew, Y.

When the machine is to be operated, 'the wire staples are placed on-thetop edge of the incline bearer E. v One after another slides down it tothe groove under the driver D. The lever C is then raised, and, with itthe cordl drawing the lever J forward against a notch" on the rod H,pushing the rod, with the slat Z behind it onkel/ notch forwardimmediately under the eye W and the staple that is ready for the driver.The lever C is then pressed Adownmpon the staple, forcing it throughthe' eye into the slat each time, at equi-distances apart, as the leverJ 'liesbackl to its place, ready to press against another notch in thetop of rodl H. The backward and forward movement of the'lever .J is alsoregulated, and prevented from moving too far forward or back byadjustable projecting pins, a, on each side, adjusted byy slot andset-screw Z.

I What I claim as my invention, and desire to secure by Letters Patent,is-

The arrangement of the cord T with the levers Gand J, and pulley S, asherein described and for the purposes set forth` ELIJAH F. DUNAWA-Y.
